Coffee Grounds – Tips and Tricks for Reusing Them

Coffee Grounds – Tips and Tricks for Reusing Them

Coffee grounds usually go straight to the trash, but there are many ways to reuse the nutrient-rich leftover coffee. We have put together seven ideas for you.

Reuse coffee grounds as a household cleaner – this is how it works

As a cleaning agent, the coffee grounds do more than some expensive household cleaners and all without chemicals.

  • The coffee grounds act like an abrasive. It is therefore particularly suitable for removing really unpleasant stains that are difficult to remove, such as burnt-in grease residues.  
  • In particularly stubborn cases, add hot water to the burnt-in remains and a good amount of coffee grounds. Let everything soak overnight. Then simply wipe the treated area. In many cases, this saves you tedious scrubbing.
  • You can also get rid of ugly deposits almost overnight. Simply put two to three tablespoons of coffee grounds in the appropriate container in the evening and leave to stand overnight. 
  • Note: Since the structure of the coffee grounds has a similar effect to scouring powder, you should not use it on sensitive surfaces or objects, e.g. made of glass or ceramic.

Use coffee grounds to drive away wasps, snails and the like

Coffee grounds are also said to have a deterrent effect on some unwelcome garden guests. The effect is controversial, but since coffee drinkers produce enough coffee grounds anyway, it is worth trying. You won’t get a cheaper deterrent, and if the trick works for you, you’re in luck.   

  • If you spread the dried coffee grounds generously around a vegetable or flower bed, this should deter ants, various types of snails and cats.
  • The coffee grounds are also said to help against wasps. Simply put the dried coffee grounds in an ovenproof bowl and light it. This should  keep most wasps off your back. Due to the smoke development, this measure is more suitable for outdoors.

Coffee grounds – the black gold for beauty

Because of its many healthy ingredients such as antioxidants, vitamins and nutrients, coffee grounds can also be used cosmetically. The coffee grounds have a slight peeling effect, so you can gently remove dead skin.  

  • For an efficient peeling mask, mix the coffee grounds with a high-quality oil, for example rapeseed or olive oil, to form a thick paste. Apply the mask to your face and cleavage. After about 20 to 30 minutes, wash off the coffee grounds mask with lukewarm water.
  • If you have dark hair, coffee grounds are the perfect hair conditioner. The treatment gives your hair a shiny shimmer, and the caffeine is said to stimulate hair growth. Massage the coffee grounds in well and let them work for about 30 minutes. Wrap the hair in aluminum foil and put a thick towel over it, the warmth of the coffee grounds will increase the positive effect. 
  • Tip: Combine the coffee grounds face mask with the hair conditioner and kill two birds with one stone.
  • You can also  add the coffee grounds to homemade soap. This not only spices up the soap on the outside: the peeling effect has a cleansing effect and the nutrients provide your hands with valuable nutrients.

Use coffee grounds to make plants bloom

Gardeners have long appreciated coffee grounds as an effective and inexpensive tool. The nutrients and trace elements contained in coffee grounds support plant growth.

  • Coffee grounds have a slightly acidic effect on the earth and also enrich the soil with humus. Coffee grounds are a valuable addition, especially for plants such as blueberries, hydrangeas and rhododendrons, which thrive particularly well on acidic humus soil.
  • With seedlings, however, you should avoid it, as the plants usually cannot tolerate the caffeine.
  • You can also enrich the soil of balcony or indoor plants with the coffee grounds. But here, too, the following applies: Only use dry coffee grounds, as otherwise mold will quickly develop and you will have the opposite effect of what you actually wanted to achieve. In addition, you should only mix in very small amounts of the dry coffee grounds sporadically, as potted plants cannot process too large amounts. If the coffee grounds decompose, they also begin to go moldy after a while.
  • Also, be sure to work the coffee grounds well into the soil. If you just sprinkle it over the earth, the positive effects of the coffee grounds cannot develop.
  • Tip: Alternatively, use cold coffee for your indoor plants. Mix the cold coffee with water in a 1: 1 ratio and water the houseplants with it every two weeks. Too often, however, you shouldn’t treat your houseplants to cold coffee.
  • Note: It is important that you dry the coffee grounds before you work them into the potting soil. Put a larger vessel in the kitchen near the heater or stove. In this way, remember to always empty the filter in the container. Ideally, you should also hang in a sieve and stir the coffee grounds occasionally so that no mold forms. You can store the dried coffee grounds in the warm boiler room, for example. Over the winter, a large amount of coffee grounds accumulates that you can use for the garden soil in spring.

Enhance compost with coffee grounds

If drying the coffee grounds is too time-consuming for you, there is another way of getting the nutrients to the plants: Simply throw the coffee grounds onto your compost heap.

  • You can also compost the filter bags, but you should pour the coffee grounds out of the filter bags, otherwise mold will quickly develop.
  • The coffee grounds accelerate the rotting of the compost and you can use them in the garden faster. However, you should mix the compost occasionally so that the coffee grounds and the other ingredients are better distributed.

Coffee grounds as an odor killer

There is hardly anyone who does not like the smell of freshly brewed coffee. The coffee grounds also have a pleasant aroma.

  • If you often process foods that have a strong odor in the kitchen, this tends to stick to the pores of your hands. Put a bowl with coffee grounds at the sink and rub it into your damp hands. Let the crowd move in for a moment. Then wash your hands as usual and all the bad smells will be gone.  
  • The odor eliminator also works great in shoes. However, it is important that you dry the coffee powder before letting it work overnight.
  • Tip: In cupboards or storage rooms that have a strange smell, it is also worth placing one or two bowls with dry coffee grounds.

Coffee grounds as a natural coloring agent

Also, to color Easter eggs with natural raw materials, the coffee grounds are suitable. The colors may not be as gaudy as with artificial colors, but it is much more natural and healthier. The eggshell is partially permeable and so parts of the dye can get inside the egg.

  • Add two liters of water with around 200 grams of coffee grounds.
  • After the water has boiled, let the mixture simmer over medium heat for a good half an hour.
  • Then put the eggs in it.
  • After about ten minutes, turn off the stove and leave the pan with the eggs on the warm plate for another 20 to 30 minutes.
